High hopes for 'Lone Ranger,' but westerns don't always score

Disney's "Lone Ranger" is opening wide this week with hopes of striking gold, but projections suggest box office glory might be more of a mirage, even while featuring the world's most bankable star.

Although they're considered a quintessential American genre, westerns don't always score big at the box office.

"Lone Ranger," starring Johnny Depp as Native American Tonto and Armie Hammer as the title character, is expected to open with a five-day $70-million take at the box office after costing at least $225 million to make.
